Abstract

A divider unit (100) for a passenger seat has a slide rail (120) that is fixed onto a side shell (12) surrounding the seat. A plate-like divider (150) is equipped with two linear guides (170) inserted in the slide rail (120) and slides within the slide rail (120). A stopper (130) attached to a front end of the slide rail (120) has a tapered surface (132), and the divider (150) is stopped when a front end of the divider (150) rides over the tapered surface (132), thereby preventing generation of collision noise.

Description

TECHNICAL FIELD
The present invention relates to a partition plate unit called a divider that is provided, for example, on a business class seat (passenger seat) arranged in a passenger cabin of an aircraft.
BACKGROUND ART

SUMMARY OF INVENTION Technical Problem
In the seats of the aircraft, reclining seats and tables must be returned to their original states during takeoff and landing. The divider must be in a stored state (initial state) during takeoff and landing, and when being used, the divider is slid frontward and abutted against a stopper to create a closed space. The divider adopts an arrangement where the divider is stopped by a stopper having high rigidity so as to satisfy demands regarding strength during collision, but when the divider is used in a normal state, the noise generated by the collision with the stopper having a high rigidity is large, and the noise becomes a problem from the viewpoint of ensuring privacy.
The object of the present invention is to provide a divider unit for seats on an aircraft that solves the above-mentioned problems.
Solution to Problem
In order to achieve the above object, the present invention provides a divider unit for an aircraft passenger seat including
a slide rail fixed to a side shell that surrounds the seat,
a plate-like slider supported by two linear guides inserted in the slide rail, and
stoppers attached to front and rear ends of the slide rail,
wherein the slide rail is a member with a C channel-shaped cross section including a slit formed at an upper portion
the linear guide is a downward T-shaped member inserted in the slide rail, and
at least a front end side stopper includes a tapered surface, a height of the tapered surface set so that a front end of the slider rides over the stopper at an end portion of the slide rail, and is increased in height toward a depth side.
Furthermore, the tapered surface of the stopper is configured of a concave-shaped curved surface.
Advantageous Effects of Invention
The present invention having the above-described arrangement enables to satisfy demands regarding strength when closing the divider, by preventing the slider from directly colliding against the stopper and absorbing impact by friction. Further, the present invention enables the divider to be stopped gradually, so that generation of collision noise can be prevented.

FIG. 2 is a configuration diagram of components of a divider.
FIG. 3 is an explanatory view of a general arrangement of the divider.
FIG. 4 is an explanatory view of a general arrangement of the divider.
FIG. 5 is an explanatory view of a relevant portion of the divider.
FIG. 6A is an explanatory view of an operation of the divider.
FIG. 6B is an explanatory view of an operation of the divider.
FIG. 6C is an explanatory view of an operation of the divider.
 DESCRIPTION OF EMBODIMENTS
A preferred embodiment of the present invention will now be described in detail with reference to the drawings.
As illustrated in FIG. 1, a passenger seat 1 of an aircraft includes a seat body 20 surrounded by a back shell 10 and a side shell 12, and a divider unit 100 is provided on the side shell 12 placed between a pair of passenger seats 1 arranged adjacent one another.
FIG. 2 illustrates an arrangement of components of the divider unit 100, wherein a side rail 120 is mounted to an upper surface of a frame 110 fixed onto the side shell 12. The slide rail 120 is a C channel-shaped rail having a groove with an opening formed on the upper portion of the side rail 20, and a flange portion 122 formed on both sides of the groove.
A divider 150 is a plate-like member, having two linear guides 170 that slide within the slide rail 120. The linear guide 170 is a downward T-shaped member, having a guide portion extending to both sides, and inserted in the inner side of the flange portion 122 of the side rail 120.
On the front end and rear end of the side rail 120 are respectively attached a front-end side stopper 130 and a rear-end side stopper 140. An upper surface of the front-end side stopper 130 is formed as a tapered surface 132, and an upper surface of the rear-end side stopper 140 is formed as a tapered surface 142.
FIG. 3 illustrates a state where a handle 152 of the divider 150 is gripped by a passenger, and the divider is slid in a direction of arrow F.
By pulling out the divider 150 frontward, the space between adjacent seats is partitioned, and privacy of the passengers is enhanced.
FIG. 4 illustrates an arrangement where a divider frame 160 is arranged at a lower portion of the divider 150.
By attaching the divider frame 160 at a lower portion of the plate-like divider 150, a rigidity of the arrangement can be enhanced.
FIG. 5 illustrates a lower portion of a front end of the divider 150 in detail.
The linear guide 170 is fixed onto the lower portion of the divider frame 160.
FIGS. 6A to 6C illustrate an operation of sliding the divider 150 in a direction of arrow F and closing the divider 150.
When the divider 150 slides on the side rail 120 and a lower surface 162 of the front end of the divider frame 160 approximates the front-end side stopper 130, since a front end portion of the tapered surface 132 of the front-end side stopper 130 is set at a lower position than the lower surface 162 of the front end of the divider frame 160, the lower surface 162 of the front end of the divider frame 160 rides over the tapered surface 132 of the front-end side stopper 130, as illustrated in FIG. GB.
Since a height position of the tapered surface 132 increases toward the depth direction, the divider frame 160 attempts to be lifted. However, since the linear guide 170 is inserted within the slit of the side rail 120, the linear guide 170 interferes with the flange portion 122 of the side rail 120, and the lifting of the divider frame is restricted.
Therefore, the lower surface 162 of the front end of the divider frame 160 is gradually slowed down by a friction force generated between the tapered surface 132 of the front-end side stopper 130, and the movement of the divider 150 to the forward direction is stopped.
By this operation, the divider frame 160 of the divider 150 and the front-end side stopper 130 are prevented from being stopped by collision, and the occurrence of noise can be prevented.
